Tin in the magnetic fraction of municipal solid waste (MSW) makes this material difficult to recycle to the steel industry. An electrolytic method using stannous fluoborate-fluoboric acid for removing tin was evaluated on a laboratory scale. Optimum concentrations of tin in the electrolyte and the effects of impurities such as aluminum, copper, iron, and lead on tin removal from the electrolyte were evaluated. Operating parameters were 60 to 65 g/l fluoboric acid and 20 to 30 g/l tin using stainless steel electrodes at a current density of 60 a/ft2. Tests were run with clean tin cans and MSW magnetics with good results. The tin content of the MSW magnetics scrap was reduced from 0.18 to 0.017 Wt % tin by reshredding, magnetic separation, and air classification, followed by electrolytic removal of the tin.
